Hi all.

I am planning a drive holiday to the German Alps this winter. Just got the service comming up and just wondering about the best oil to put in. I have seen the Valvoline VR1 20W/50 recomended, but in the handbook tells me, that the 20W/50 oil is too thick at cold temperatures.
Any suggestion for the best oil to use, if you drive in colder climate?
Also, anybody fancy comming along? I love the real snow.....:welcome2:

Do not use 20w50

15w-40 is the standard recommendation for that engine

10w-40 semi synthetic would be better and 5w-40 fully synthetic would be the best with the lowest pour point of all of them

If you can afford it go with a good 5w-40 fully synthetic
 
There has been numerous threads on this subject/argument as to what's the best oil. The main concensus of opinion (for the UK at least) seems to be 20W50 is perfectly adequate as the engine was designed in the 50s/60s when synthetic oils were a twinkle in someones eye. Modern engines with their much much closer tolerances and clearances do require the semi synthetic or fully synthetic oils but a 50 year old design?
Looking at (the US version of) Rave, they recommend a standard oil of 5W40 or 5W50 but this takes it down to -22deg F (-30degsC) Warmer climes allow for 10W40 to 10W60 which allows for 14degsF or -10degsC.
Personnal choice at the end of the day.
 
10/40 semi synthetic my choice as cheap **** mineral oil ashes and the oil I suggest is cheap enough

Although the engines history can be traced back to the fifties the internals are not the same and have been manufactured with modern tools to closer tolerances to what they were back then.

An oils pour point is about 10 to 15 degrees colder than the temp at which it's thin enough to pump. A 20w50 at 0 degrees with most probably be like thick treacle if it's a mineral oil.

Bollix!

A 20w50 oil is the same viscosity as any other 20w50 oil, irrespective of type. Thats wot the 20 & the 50 stand for.
I suggest yu read Dafts guide to oil in the FAQ section. :rolleyes:
Look on www.castrol.com to find recomended oil for your registration number.

A PAO synthetic 20w-50 will have a pour point of about-45 degrees C

A Mineral 20w-50 will not

at 40 degrees they will both be a 20w but a synthetic will thicken much less than a mineral oil when temps are around 0 degrees
